SPECIFICATION forming part of Letters Patent No. 627,373, dated J une20, 1899.

To @ZZ whom, t may concern:

Be it known that I, CHARLES THOMAS WISE, Sr., of New Bridge, in thecountyof Union and State of Oregon, have invented anew and ImprovedHeater, of which the following is a full, clear, and exact'description.

The object of the invention is to provide a new and improved heaterwhichis simple and durable in construction, serviceable as a hot air or waterheater in the form of a stove, furnace, boilers, drying apparatus, orthe like, and arranged to utilize the fuel to the greatest advantage.

The invent-ion consists of novel features and parts and combinations ofthe saine, as will be fully described hereinafter and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of the improvement arranged as a hot-waterheater. Fig. 2 is a sectional side elevation of the same on the line 2 2of Fig. 3. Fig. 3 is a transverse section of the same on the line 3 3 ofFig. 2. Fig. 4 is asectional side elevation of the improve! mentarranged as an air-heater, and Fig. 5 is an enlarged side elevation ofpart of the saine.v

The improved heater, as shown in Figs. 1, 2, and 3, is provided with acasing A, supporting a tank B, adapted to contain water to be heated,the lower end of said tank being connected with one end of a pipe O,-extending in a longitudinal direction in the casingA to the forward endthereof, to be then formed into a coil C', arranged centrally in thecasing, and preferably round or square in form. The rear end of the coilO terminates in a horizontally-disposed coil O2, located in the upperportion of the casing A, and the end of said coil passes through thecasing'and extends up and down around the casing to form connectedradiators C3 through which circulates the water or other heating mediumfor giving off heat to the surrounding air in the room. The end O4 ofthe last radiator Os returns into the tank B, so that the water iscirculated from the tank through the several 5o parts of the pipe C andback to the tank.

The latter is provided on its top with a illing-cap D and with asafety-valve E, to allowi steam to escape in case it is formed.

The coil C is surrounded by a jacket formed bya shell F, attached at itsforward end to a cap G for closing the front end of the casing A, and onthe said cap Gis arrangedaiiringdoor l-I for introducing the necessaryfuel into the fire-box formed by the said coil O. The inner end of theshell F terminates on a transverse partition or iiange J, located at theend ofthe coil O'. rlhe object of the jacket is to confine the heat tothe iirebox to better control the draft and to guard against leakage ofashes, coal, dac., should the layers of the coil C spring apart orbecome displaced by the heat of the burning fuel.

If the heater is to be arranged as an air- 'heater, as shown in Figs. 4and 5, then the .of the last radiator O3 terminates in branch pipes O5O6, provided with valves O7 and C8, respectively, and passing into theforward end of the casing. The branch pipe O5 then eX- tendslongitudinally in the coil O/ along the upper portion thereof toterminate in a downward bend O9, opening into the forward end ot' thetire-box to supply the latter with air for the proper combustion of thefuel. The other branch pipe CG discharges air into the forward port ofthe casing at or under the coil O2. Now by opening the valve C,T andclosing the valve C8 the air passes to the firebeX, and by closing thevalve O7 and opening the valve OS the air passes to the front end of thecasing. In either case the air discharged by the pipes C5 and C6 servesto aid combustion and regulate the draft.

The rear end of the casing A is provided with a chimney-fine L forcarrying off the smoke and gases, and in the rear end of the shell A isalso arranged a door N for giving access to the interior of the casingand reF box for cleaning the same whenever desired.

Now it will be seen that by the arrangement described the fuel in thefire-box formed by the coil O thoroughly heats the water or IOO airflowing through the pipe C and coil C' to establish a circulation of theheating medium, as previously explained. As the heated air or watercirculates through the radiators C3 a large amount of heat is given o tothe surrounding air, so that the room in which the heater is located isvery quickly and thoroughly heated With a comparatively smallexpenditure of fuel. It' desired, proper connection can be made With`the pipe forming the radiators C3 for leading the heated air or water toa distant place for supplying a radiator there.

A draft-pipe similar to the pipe C5 is preferably made use of in theWater-heater to supply the fire-box C with fresh heated air to aidcombustion.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A heating apparatus having a casing, a jacketlocated in the casing and separated from the walls thereof, andoccupying a portion of the space Within the casing, and afluidcirculating tube extended into the casing through the jacketthereof and formed into a vertical coil Within said jacket, the tubebeing extended from said vertical coil to the front portion of thecasing and being there formed into a horizontal coil, from whichhorizontal coil the tube passes without the casing and is bent-intovertically-disposed loops eX- tending around the casing to formconnected radiators.

2. A heating apparatus having a casing, a jacket situate therein andoccupying a portion of the space therein, the jacket being separatedfrom the walls of the casing, a tube extended into the casing andthrough the jacket thereof, the tube being formed intovertically-disposed coils within the jacket and being extended from saidjacket to the frontof the casing and formed into horizontallydisposedcoils from Which the tube passes Without the casing and is formed intovertically-extending bends forming radiators eX- tending around thecasing,the end of the tube being formed into two branches returned intothe casing and discharging, the one into the coil of the jacket, and theother beneath the horizontal coil of the casing, and valves respectivelycommanding the said branches.
